Firmware update indicator

When D'CENT adds support to a new blockchain network, a new firmware will be available for installation. Your mobile app will show an indication when a newer version of the firmware is released.

Before you update the firmware

Make sure you have your Mnemonic Code (24 seeds/words) for recovery

24 words were provided during the Initial Setup of your Biometric Wallet and you have written them down on the recovery card. Make sure you still have the recovery card before you proceed with the firmware update. Unlike other products, your wallet will still remain safely intact inside the secure chip even after updating the firmware. This means that you don't need to recover your wallet every time you update the firmware as other products requires you to do.

After you update the firmware, you cannot roll-back to the previous version

To perform the firmware update, it is recommended to use the original D'CENT OTG cable. Firmware update will take approximately 5~10 minutes to complete.
